PiPE, mum-Ron, AND CASING PULLER.

Too whom, it may concern Belt known that I, Josm'u' SAUL GEN- nnosgacitizen of the United 'Statesfresidnods or casings-for permitting theNorth I)akota, ha\1e invented ,a new Pipe;

lh-ill-llod, andC asing Puller of .Whiclr the I following is aspecification.

This invention relates to form of pipe. drill rod and casing puller orextractor,capable of-being easily and quicklyengaged with sectionsoff-pipes, drill lifting or extracting of the same from theboflr and for'allowing "the same. to b.e freel \7 rotated in order that thecouplingsof other sections which may be engaged therewith and bedisengaged therefromw Another "ai id equally i n'i portant object-ofcthe 'inrention' is to proridei a dei'icefofthe character mentionedwhich when engaged with an object will have the line of pull directed-to the center of said object and as a consequence,"materiallyfacilitatethe removal thereof,

' Applicatioii filed'Deceinber 26, 1917. Serial No. 208,891.

' The spaced sides of the iooped bed are otfset' as at 3, preferably atpoints intermediate the upper and lower ends, and as will be noted,"arespaced suflicie itly to allow the coupling element, which is of adiameter greater than the diameter of the pipe, drill rod or casingengaged thereby to pass therethrough andin this way cause said couplingelement to be loosely seated on said segmental jaw-2.

The upper end of the looped body 1- is elf-settherefrom as at l and isarranged in \'ertic al al uenz' at with the center ofthe vjaw '2.'l'len'cc, when a cable or like connection 5 is secured thereto and disrendered taut to support the device. the resultant line fpilll or'drafiwill be accurately ceiitere 'l' with respect to theccnter of the'jaw andthe object engaged orresting thereon and to be lifted thereby.

From the foregoing, by those skilled in the artthat l have pro i'dcd anexceedingly sim-pleand efficient derice for use in lifting. removing ,orextract,- ing pipe's,' drill rods or casings from the bores of wells,the same by reason of its construction, being capable of being quickl)and readily engaged-with an'objcct. thus. rendering it desirable for useas a picking tool also. Further, due'tothe manner in which the device isengaged "with an object. sai i'l object can be freely rotated 'in theevent that it ,is necessarv to disengage or uncouple to the particularembodiment chosen for illustration herein, nor-to the exactconstruction.arrangement and adaptation of parts shown and described, butl reservethe right to-makc an cluingcs illlll'tllttl'illlOllH that fairly fallwithin the spirit and scope of the invention. r r
